Waiting for official Android upgrades is not something is not what an
Android geek prefers, he scounders the internet for Custom ROMs already
running on the latest Android version and flashes it on his phone. If
you reached here scoundering for the same thing, you won’t be
disappointed. By following the simple steps we are gonna provide later
in this article, you will be proudly running the latest Android 4.2.2
Jelly Bean on your Galaxy Note II. Note II users don’t need a custom rom
to boost performance – I have hardly seen any lag on a Note II – they
need them to get awesome new features, some lifted from other phone,
some that are exclusive to particular custom roms. Like, say, Paranoid
rom allows user to run apps at specific DPIs allowing you to run Chrome
in tablet mode while the Clock still runs in phablet mode.

Before you proceed:

+ Backup all your data that you won’t want to loose. Flashing a
custom rom will format all your partitions except the internal sd card,
and of course the external sd card. Titanium Backup is a really good app
for this job.

+ Root your Samsung Galaxy Note II using the guide linked at the start of the article.

+ Charge your phone sufficiently before starting with the ritual.
